Having thus described my invention, I claim as new and desire Patent:

In a coupling,

I s, flexible connecting members connecting the ysaid coupling memberswith eachother, each flexible con'- necting member having a plurality ofsuperimposed Hat springs, keepers on ,ing members F each formed of aplurality of superimposed vflat steel springs F- fitt'ngat their endsinto forks of keepers F2 and F provided with transverse pins Gr, Gpassing through elongatedslots F4, F arranged in a series ofsuperimposed fiat springs vF,.ae will be readily understood by referenceto Figs. 2 and 3.

y The keepers VF12' F3 are, preferably cylindrical and tit .intocorresondi-ngly-shaped -ersengaging recesses in the faces of the saidcoupling members,I and a connection between one of the keepers of eachconnecting mem- 'ber and the corresponding cou ling member for.preventing theconnecti formed in the. f

hold the said l that they flex on vthe pins G i 'mitsits use on shaftsdriven at low or high v 95 the ends of; the said superimposed flatsprings, the keep g members.

The coupling shown and described is very to secure by Letters lio'netting 2. in a coupling, the combination ofcoupling members adapted tob'e secured to thel adjacent ends of two shafts, flexible connectingmembers connecting, the said coupling members with each other, eachfiexible con ln ecting member lhaving a plurality of superimposed flatsfrings provided near their ends with elongated slots, keepers receivingtheends of the said fiat springs of each connecting member, pins on thekeepers and extending ,through the said flat Spring slots, and aconnection between one of the keepers of each connecting member and thecorresponding vcoupling member for preventing the connecting membersfrom turnsaid coupling members With each other, each flexible connectingmember having a plurality et superimposed dat springs, keepers on theends of the said superimposed dat springs, the keepers engaging recessesiii-the faces of the said coupling members, and means on one of thekeepers-ofeach connecting member and engaging the 'said ring for holdingthe connecting vmembers against turning in the coupling members. l at.In a coupling, the combination of coupiing disks adapted to be securedto the adjacentends of two shafts, iexibie connecting members eachhaving keepers .at the ends thereof, the keepers iit'ting intocorresponding recesses in the coupling disks and a ring on the outerface of one of said disks and provided with a groove, one of the keepersof each connecting member having an extension fitting in tbe groove otlthe'said ring.

in a coupling, the combination of coupling members adapted to be securedto the adjacent ends of two shafts, fiexible connecting membersconnecting the said coupling members with eachother, each flexible con-`perirrngosed fiat springs, the Saidconnecting members being arranged ina circle and the :dat springs being capable' of tl'exing in thedirection o t 'the turning movementof the coupling, and keepersin ywhichthe ends/of the springs.oteacireonnecting member are l y in positionmember vhaving a plurality of suheld, the keepers slidingly engagingrecesses in the said coupling members, one of the keepers of eacliconnecting member be'ng provided With a fiat offset fitting a groove inthe corresponding coupling member.

6. In a coupling, the combination of coupling disks adapted to besecured to the adjacent ends of shafts to be coupled, the disksbeingprovided on their opposite faces with recesses arranged in circlesnearthe margins of thedisks, a ring on the outer face of one ofsaidqtlisks, the ring being provided with an annular groove registeringwith the recesses in the disk, and connecting members connecting thecoupling disks With each other, cach connecting member comprising aseries ot' superimposed flat springs and keepers von the ends of theseries of springs, the keepersengaging the recesses in the said disksand one'oi the keepers having a iiat offset extending into the vgrooveof the said ring to hold-the iiat springs approximately to' iex' in thedirection of the turningvmovement of the coupling.
